This makes me think they are talking about if you have any issues that make SW the wrong career choice... or issues you need to seriously reflect on. These questions are actually intended to teach you... to begin your training.

So... in the interest of writing a competitive application essay, do a good job of self-analysis. Dig deep, and think about bias you may be susceptible to, strong feelings you have, etc... anything you feel passionate about can help or hurt you. Dig deep, and share some introspection.

:-)

That is how to impress them. And read some books or articles about emotional struggles faced by people in this profession... reading about them will guide your self-analysis.
